|The US Patent and Trademark Office has finished a re-examination of Apple's so-called "Steve Jobs patent" and upheld all 20 claims as patentable, reports note. The patent is 364 pages in length, and covers many of the core concepts of the iPhone. Last year it was challenged anonymously, however, and in December the USPTO issued a preliminary invalidation.
The re-examination certificate was quietly issued to Apple on September 4th. The decision should give Apple a more solid legal standing in lawsuits. It's not clear who made the anonymous challenge, but it's speculated to be Samsung and/or Google, both of whom have been the main targets of Apple legal attacks over Android. Jobs famously accused Android of being "stolen," and threatened to go to "thermonuclear war" over his beliefs.
